The Apple Watch needs an iPhone to work; that’s how it has always been. You can’t use it with an Android device, and that’s apparently a big problem for the US government. It’s one of the reasons the Justice Department sued Apple. The DoJ’s big antitrust case was officially announced on Thursday.
It’ll be a long and arduous fight that might take years to resolve. It’ll be years until Apple will have to make changes to the products it sells in the US, and that’s if the DoJ is successful in any of its claims.
